The LT
1678/LT1679 are dual/quad rail-to-rail op amps
offering both low noise and precision: 3.9nV/√Hz wideband
noise, 1/f corner frequency of 4Hz and 90nV peak-to-peak
0.1Hz to 10Hz noise are combined with outstanding
precision: 100V maximum offset voltage, greater than
100dB common mode and power supply rejection and
20MHz gain bandwidth product. The LT1678/LT1679 bring
precision as well as low noise to single supply applications as
low as 3V. The input range exceeds the power supply by
100mV with no phase inversion while the output can swing
to within 170mV of either rail.
The LT1678/LT1679 are offered in the SO-8 and SO-14
packages. A full set of matching specifications are also
provided, facilitating their use in matching dependent appli-
cations such as a two op amp instrumentation amplifier
design. The LT1678/LT1679 are specified for supply volt-
ages of ±15V, single 5V as well as single 3V. For a single
amplifier with similiar performance, see the LT1677 data
sheet.
